Slight reordering of directories searched for BerkDB libs and include files.

Push /usr/... further down the list - always check /usr/local/... before

Doubt this will help with http://python.org/sf/589427 or not, but these
changes were prompted by my investigation of that bug report.  I wasn't able
to reproduce that problem though
